UAV Detection Using Multi-Sensor Segmentation and Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The anonymous nature of unmanned aerial vehicles (UAVs) poses challenges in ensuring airspace safety and accountability, particularly in regulated areas like airports, prisons, and residential homes, as existing systems lack effective methods for identifying, tracking, and managing UAVs to differentiate between malicious and benign operations.
Innovation Solution
A system utilizing a plurality of sensors, including video, audio, Wi-Fi, and radio frequency (RF) sensors, combined with portable countermeasure devices, to detect, identify, track, and manage UAVs by collecting and processing data to recognize and disrupt unauthorized UAVs within specific airspaces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If multiple sensors are deployed to detect and identify UAVs, then measurement precision and reliability improve, but device complexity and cost increase
Solution Approach 1:
The system divides UAV detection into multiple independent sensor modules (video sensor, audio sensor, Wi-Fi sensor, RF sensor), each specializing in detecting specific characteristics of UAVs. This segmentation allows each sensor to focus on particular aspects of UAV identification while collectively providing comprehensive detection capabilities.
Solution Approach 2:
The sensor system is designed to perform multiple functions simultaneously: detecting UAV presence, identifying UAV type, tracking UAV location, and monitoring UAV communication signals. This multi-functionality reduces the need for separate specialized systems while improving overall detection precision.
2Reliability
If countermeasure devices are used to disrupt unauthorized UAVs, then airspace safety improves, but potential harm to benign UAV operations increases
Solution Approach 1:
The system continuously monitors UAV identification data and operational characteristics, using this feedback to adjust countermeasure application. By analyzing real-time data about UAV behavior, communication patterns, and flight paths, the system can distinguish between malicious and benign operations before applying countermeasures.
Solution Approach 2:
The countermeasure device can adjust its disruption parameters (frequency, power, duration) based on the identified UAV type and threat level. This allows selective application of countermeasures tailored to specific unauthorized UAV characteristics while minimizing impact on benign operations.
Data Source
AI summary
Systems, methods, and apparatus for identifying, tracking, and disrupting UAVs are described herein. Sensor data can be received from one or more portable countermeasure devices or sensors. The sensor data can relate to an object detected proximate to a particular airspace. The system can analyze the sensor data relating to the object to determine a location of the object and determine that the object is flying within the particular airspace based at least in part on location data. A portable countermeasure device can be identified that corresponds to the location of the object. The system can transmit information about the object to the identified portable countermeasure device. The portable countermeasure device can transmit additional data relating to the object to the system.
